Internal worker function that reports a status code through the Status Code Protocol
Internal worker function that reports a status code through the PEI Status Code Service or
OEM Hook Status Code Library.
This function checks to see if a Status Code Protocol is present in the handle
database. If a Status Code Protocol is not present, then EFI_UNSUPPORTED is
returned. If a Status Code Protocol is present, then it is cached in gStatusCode,
and the ReportStatusCode() service of the Status Code Protocol is called passing in
Type, Value, Instance, CallerId, and Data. The result of this call is returned.
This function first tries to report status code via PEI Status Code Service. If the service
is not available, it then tries calling OEM Hook Status Code Library.
